Abstract

The invention relates to an industrial wireless network service adaptation method based on an OPC-UA service platform. The method comprises the following steps: firstly, initializing operation parameters, storing the operation parameters into a sharing memory, and initializing working states of various communication ports and protocols according to the various operation parameters in the sharing memory; reconfiguring the own working states of the communication ports and the protocols along with changes of the operation parameters in the sharing memory during working; and managing the operationparameters in the sharing memory through an OPC-UA monitoring method. The industrial wireless network service adaptation method based on the OPC-UA service platform increases the intelligence degreeof a production process, performs fine granularity monitoring and integral optimization on a production system, provides the fusion capacity for various transmission technologies in a multi-state network architecture, and improves the communication capacity among equipment.

Description

technical field [0001] The invention relates to the field of wireless and wired communication in industrial control, in particular to an industrial wireless network service adaptation method based on an OPC-UA service platform. Background technique [0002] At present, in metallurgy, petrochemical and other production systems, the phenomenon of manual meter reading still exists in large numbers. This shows that the degree of intelligence in the production process of my country's process industry is still very low, and in many complex and multi-link production systems, fine-grained control has not been achieved. In order to achieve the fine-grained control of the complex production system and the collaborative optimization of multiple links, it is necessary to realize the unified collection and control of multi-link production parameters, and the unified networking of each production process equipment. However, the status quo of the current industrial production environment ...
